Antigen-specific immunosuppression can be enhanced by genetically modifying mesenchymal stromal cells with chimaeric antigen receptors, as shown for the treatment of graft-versus-host disease in mice.

Noninvasive spinal stimulation improves walking in chronic stroke survivors: a proof-of-concept case series

After stroke, restoring safe, independent, and efficient walking is a top rehabilitation priority. However, in nearly 70% of stroke survivors asymmetrical walking patterns and reduced walking speed persist. Th…

Nature Biomedical Engineering, Published online: 27 March 2024; doi:10.1038/s41551-024-01192-9

By coating manganese dioxide on the surface of fixed bacteria, we obtained mineralized bacteria with the ability to potently activate multiple immune signalling pathways. Immunotherapy with mineralized bacteria suppressed various types of cancer in multiple animal models, eliciting both immune memory and abscopal antitumour effects.

While pacemakers have been instrumental in treating many patients with heart rhythm disorders, their bulky design and dependence on wires can limit their usefulness and poses a risk of heart damage or infection. Researchers have cut the cords, shrunk the size, and expanded the capabilities of current designs.

Bioelectronic mesh capable of growing with cardiac tissues for comprehensive heart monitoring

clehmann

A team of engineers led by the University of Massachusetts Amherst and including colleagues from the Massachusetts Institute of Technology (MIT) recently announced in the journal Nature Communications that they had successfully built a tissue-like bioelectronic mesh system. The mesh can grow along with the cardiac cells, allowing researchers to observe how the heart's mechanical and electrical functions change during the developmental process.
